Subject: [PATCH] vif queue counters from int to long

From: Mart van Santen <[email-masked]>

Hello,

This patch fixes an issue where counters in the queue have type int,
while the counters of the vif itself are specified as long. This can
cause incorrect reporting of tx/rx values of the vif interface.
More extensively reported on xen-devel mailinglist.
